The Delhi government has made it mandatory for all hospitals and laboratories to record blood oxygen saturation levels of every person being tested for the coronavirus (Covid-19) disease in a bid to ensure needy patients get medical attention on time. Covid -19 centers or hospital should mandatorily check the oxygen level of the people, and person who found having it below 94% must undergo further medical examinations. Delhi health minister Satyendar Jain tweeted on Tuesday and shared the copy of the order.
